Information on the type of service and service
intervals (see the separate Maintenance Book-
let).
You can obtain further information from an
authorized Mercedes-Benz Center or at
http://www.mbusa.com (USA only).
i The ASSYST PLUS service interval display
does not show any information on the engine
oil level. Observe the notes on the engine oil
level ( Y
page 331).
The multifunction display shows a service mes-
sage for several seconds, e.g.: R
Service A in XX Days R
Service A Due R
Service A Overdue by XX Days
Depending on the operating conditions of the
vehicle, the remaining time or distance until the
next service due date is displayed.
The letter A or B , possibly in connection with a
number or another letter, indicates the type of
service. A stands for a minor service and B for a
major service.
You can obtain further information from an
authorized Mercedes-Benz Center.
The ASSYST PLUS service interval display does
not take into account any periods of time during
which the battery is disconnected.
Maintaining the time-dependent service sched-
ule: X
Note down the service due date displayed in
the multifunction display before disconnect-
ing the battery.
or X
After reconnecting the battery, subtract the
battery disconnection periods from the ser-
vice date shown on the display.
Hiding a service message X
Press the v or 8 button on the steering
wheel.
Displaying service messages X
Switch on the ignition. X
Use
or waxes. There is otherwise a risk of damag-
ing the surface.
! Do not use chrome polish on trim pieces.
The trim pieces have a chrome look but are
mostly made of anodized aluminum and can
lose their shine if chrome polish is used. Use
a damp, lint-free cloth instead when cleaning
the trim pieces.
If the chrome-plated trim pieces are very
dirty, you can use a chrome polish. If you are
unsure as to whether the trim pieces are
chrome-plated or not, consult an authorized
Mercedes-Benz Center. X
Wipe the wooden trim and trim pieces with a
damp, lint-free cloth, e.g. a microfiber cloth. X
Trim elements with piano black finish:
clean with a soft, damp cloth and a commer-
cially available soap solution. X
Heavy soiling: use care and cleaning prod-
ucts recommended and approved by
Mercedes-Benz.
Cleaning the seat covers
General notes
! Do not use a microfiber cloth to clean covers
made out of real leather, artificial leather or
DINAMICA. If used often, these can damage
the cover.
Note that regular care is essential to ensure that
the appearance and comfort of the covers is
retained over time.
Genuine leather seat covers
! To retain the natural appearance of the
leather, observe the following cleaning
instructions: R
Clean genuine leather covers carefully with
a damp cloth and then wipe the covers
down with a dry cloth. R
Make sure that the leather does not
become soaked. It may otherwise become
rough and cracked. R
Only use leather care agents that have
been tested and approved by Mercedes-
Benz. You can obtain these from a qualified
specialist workshop.
Leather is a natural product.
It exhibits natural surface characteristics, for
example: R
differences in the texture R
marks caused by growth and injury R
slight nuances of color
These are characteristics of leather and not
material defects.
Seat covers of other materials
! Observe the following when cleaning: R
clean artificial leather covers with a cloth
moistened with a solution containing 1%
detergent (e.g. dish washing liquid). R
clean cloth covers with a microfiber cloth
moistened with a solution containing 1%
detergent (e.g. dish washing liquid). Rub
carefully and always wipe entire seat sec-
tions to avoid leaving visible lines. Leave
the seat to dry afterwards. Cleaning results
depend on the type of dirt and how long it
has been there. R
clean DINAMICA covers with a damp cloth.
Make sure that you wipe entire seat sec-
tions to avoid leaving visible lines.
Cleaning the seat belts
G WARNING
Seat belts can become severely weakened if
bleached or dyed. This could cause the seat
belts to tear or fail, for instance, in the event of
an accident. This poses an increased risk of
injury or fatal injury.
Never bleach or dye the seat belts.
! Do not clean the seat belts using chemical
cleaning agents. Do not dry the seat belts by
heating at temperatures above 176 ‡( 80 †)
or in direct sunlight. X
Use clean, lukewarm water and soap solution.
Cleaning the headliner and carpets X
Headliner: if it is very dirty, use a soft brush or
dry shampoo. X
Carpets: use the carpet and textile cleaning
agents recommended and approved by
Mercedes-Benz. Care 341
Maintenance and care Z
Flexible Fuel vehicles can be refueled with the
following fuel types: R
premium-grade unleaded gasoline R
E85 fuel R
a mixture of E85 fuel and premium-grade
unleaded gasoline
i Flexible Fuel vehicles can be recognized by
the Ethanol up to E85 sticker on the inside of
the fuel filler flap.
Fuel consumption The energy content of E85 fuel is less than that
of the same amount of premium-grade gasoline.
The amount of fuel consumed when operating
the vehicle with E85 fuel is therefore higher than
with premium-grade gasoline.
Maintenance Inform your authorized Mercedes-Benz Center
that you are operating or have operated the
vehicle with E85 fuel.
Low outside temperatures If the outside temperature is below 32 ‡( 0 †),
the starting procedure can take noticeably lon-
ger when operating with E85 fuel.
E85 fuel is not suitable for use at outside tem-
peratures under -4 ‡ (-20 †).
Engine oil
General notes
! Never use engine oil or an oil filter of a spec-
ification other than is necessary to fulfill the
prescribed service intervals. Do not change
the engine oil or oil filter in order to achieve
longer replacement intervals than those pre-
scribed. You could otherwise cause engine damage or damage to the exhaust gas after-
treatment.
Follow the instructions in the service interval
display regarding the oil change. Otherwise,
you may damage the engine and the exhaust
gas aftertreatment.
When handling engine oil, observe the important
safety notes on service products ( Y
page 388).
The engine oils are matched to the performance
of Mercedes-Benz engines and service intervals.
You should therefore only use engine oils and oil
filters that are approved for vehicles with main-
tenance systems.
For a list of approved engine oils and oil filters,
consult an authorized Mercedes-Benz Center.
Or visit the website

Important safety notes
G WARNING
Windshield washer concentrate could ignite if
it comes into contact with hot engine compo-
nents or the exhaust system. There is a risk of
fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.
! Only use washer fluid that is suitable for
plastic lamp lenses, e.g. MB SummerFit or MB
WinterFit. Unsuitable washer fluid could dam-
age the plastic lenses of the headlamps.
! Do not add distilled or de-ionized water to
the washer fluid container. Otherwise, the
level sensor may be damaged.
! Only MB SummerFit and MB WinterFit
washer fluid should be mixed together. The
spray nozzles may otherwise become
blocked.
When handling washer fluid, observe the impor-
tant safety notes on service products
( Y
page 388).
At temperatures above freezing: X
Fill the washer fluid reservoir with a mixture of
water and windshield washer fluid, e.g. MB
SummerFit.
Add 1 part MB SummerFit to 100 parts water. At temperatures below freezing: X
Fill the washer fluid reservoir with a mixture of
water and washer fluid, e.g. MB WinterFit.
For the correct mixing ratio refer to the infor-
mation on the antifreeze reservoir.
i Add windshield washer fluid, e.g. MB Sum-
merFit or MB WinterFit, to the washer fluid all
year round.
Climate control system refrigerant
Important safety notes The climate control system of your vehicle is fil-
led with refrigerant R ‑ 134a.
The instruction label regarding the refrigerant
type used can be found on the radiator cross
member.
! Only the refrigerant R ‑ 134a and the PAG oil
approved by Mercedes-Benz may be used.
The approved PAG oil may not be mixed with
any other PAG oil that is not approved for
R-134a refrigerant. Otherwise, the climate
control system may be damaged.
Service work, such as topping up refrigerant or
replacing components, may only be carried out
by a qualified specialist workshop. All applicable
regulations, as well as SAE standard J639, must
be adhered to.
Always have work on the climate control system
carried out at a qualified specialist workshop.
